The White Knight - Russell Johnson - Bog

At the age of eleven, Jonathan Wright began to time travel. He unraveled a struggle between good and evil that pitted a demonic spirit of desolation against an angelic being of light.
Jonathan got caught in the middle, and the evil Abomination made this struggle a personal one by murdering Jonathan's family. The angelic Guardian sends him on a quest through time to find the way to kill the demon. During the time of the cataclysmic flood of Noah, he discovers the way to defeat the demon, but it comes at a high price. Innocent blood must be shed, and his rash actions plunge mankind into a downward spiral of bondage to the ruin of the Abomination. He is in danger of becoming corrupted by the demon he swore a vow to destroy, all because he desires to win the love of a woman he cannot have. The choice between saving one innocent girl, or saving the world, makes the White Knight a thrilling ride through time.
